Threshold for photoelectric emission from a quantum ring of narrow-gap semiconductor

In this paper, we have investigated the threshold energy required for photoelectric emission of electrons from a torroidal quantum ring of degenerate narrow-gap semiconductor. Current density due to electrons emitted from the ring illuminated by normal radiation has been calculated considering the e...
